Seeing as a week from today we'll be studying the landmark third brass quintet by Viktor Ewald, I thought a fantastic recording of his first would inform that class.
This is another favorite recording of mine. I would encourage you to listen to it somewhere other than the youtube link above as the quality is severely lacking.
Some background on the recording: This was done live in 1966 in Chicago with the brass quintet composed of members of the CSO. Trumpets, Adolph Herseth and Vincent Cichowicz, horn, Richard Oldberg, trombone, Frank Crisafulli, and the legendary player and pedagogue Arnold Jacobs on tuba.
Once again the sense of connection and intimacy is so present in this playing. These artists know the ins and outs of each others sounds and how to create a phenomenal ensemble playing rather that presenting 5 soloists.
